"It’s a huge problem in New York City. Sketchy slumlords freeze their (usually poor) tenants to save money and/or drive them out of their buildings to raise rents. The health effects of being “fuel poor” are well documented. But when freezing tenants complain in court, it’s their word against that of their legal-savvy landlords.

Unless there’s hard data proving otherwise."

World's first process to reuse rare Earth metals extracted from nickel-metal hydride batteries for hybrid vehicles
"the rare earth metals were extracted from nickel-metal hydride batteries collected from 386 Honda hybrid vehicles that were stored prior to being on sale but became unusable by the Great East Japan Earthquake. Further, as soon as a sufficient volume is secured, Honda will begin applying the same process and recycle rare earth metals extracted from used nickel-metal hydride batteries collected by Honda dealers through battery replacement."

The nuclear reactor in your basement
"How would you like to replace your water heater with a nuclear reactor? That's what Joseph Zawodny, a senior scientist at NASA's Langley Research Center, hopes to help bring about. It would tap the enormous power of the atom to provide hot water for your bath, warm air for your furnace system, and more than enough electricity to run your house and, of course, your electric car."

"An artificially excavated limestone pit in the south of France will soon host star-making technology, New Scientist reports. "If all goes well," the magazine explains, in a few year's time the pit will "rage with humanity's first self-sustaining fusion reaction, an artificial sun ten times hotter than the one that gives our planet life.""

Guernica / White on Noir
"...the town is a post-apocalyptic industrial hellhole. When you first get there you think, “This is the ugliest place I’ve ever seen. There’s nothing attractive about it, there’s nothing inviting, let’s just leave.” After two hours, you realize that every place you’re going is numbered, as if you’re inside the guts of a circuit board or you’re living in a combination lock. The two people I was traveling with would send me a text, “Oh we’re in Region 8” or “Come meet us at 8174.” After the first three or four hours we started looking around and saying “Oh my god, we’re in an Alphaville set...”"

Legacy of nuclear drilling site in Colorado still lingers | MNN - Mother Nature Network
"In 1969, the US government detonated a subterranean nuclear bomb to break loose natural gas deposits from tight sandstone formations more than 8,000 feet below ground on a Colorado mountain. The bomb was twice as powerful as the one that destroyed Hiroshima, Japan, in 1945."

Energy in Chile: Dancing in the dark | The Economist
"ON THE evening of September 24th a power cut plunged almost 10m Chileans, more than half the population, into darkness. Copper mines shut down, traffic lights failed and Saturday night revellers in Santiago found themselves dancing in the dark. Power was restored within a few hours, but the blackout was a worrying foretaste of what may be to come."

'Darker-than-black' metamaterial could lead to more efficient solar cells
"(PhysOrg.com) -- If typical black paint absorbs about 85% of incoming light, then a newly designed metamaterial that absorbs up to 99% of incoming light may be considered “darker than black." By taking advantage of the unique light-scattering properties of metamaterials, researchers have discovered that a hyperbolic metamaterial with a corrugated surface can have a very low reflectance, which could make it promising for high-efficiency solar cells, photodetectors, and radar stealth technology."

New reactor paves the way for efficiently producing fuel from sunlight
"Using a common metal most famously found in self-cleaning ovens, Sossina Haile hopes to change our energy future. The metal is cerium oxide—or ceria—and it is the centerpiece of a promising new technology developed by Haile and her colleagues that concentrates solar energy and uses it to efficiently convert carbon dioxide and water into fuels."
